Troubleshooting
June 2019
• In low-frequency meters, tube fouling
Recommended actions
1. Ensure that all of the calibration parameters have been entered correctly.
See the sensor tag or the calibration sheet for your meter.
2. Purge the sensor tubes.
3. Check for coating in the flow tubes.
4. Perform Smart Meter Verification.
16.5.4 Unusually low density reading
Cause
• Two-phase flow
• Incorrect calibration factors
• In low-frequency meters, erosion or corrosion
Recommended actions
1. Check your process conditions against the values reported by the device.
2. Verify all of the characterization or calibration parameters. See the sensor tag or the calibration sheet
for your meter.
3. Check the wiring between the sensor and the transmitter.
4. Check for tube erosion, especially if the process fluid is abrasive.
5. Perform Smart Meter Verification.

16.6 Discrete Output problems

16.6.1 No Discrete Output
Cause
• Output not powered
• Wiring problem
• Channel not configured for desired output
• Channel not licensed
• Circuit failure
Recommended actions
1. Check the power supply and power supply wiring.
2. Verify the output wiring.
3. Verify that the channel is wired and configured as a Discrete Output.
4. Purchase a license for the channel and upgrade the transmitter firmware.
5. Contact customer service.
